Honestly, I question the severity of the last column. Did anyone think Taylor Swift wasn't on the left before endorsing Harris? Did anyone doubt where Elon Musk stood before he endorsed Trump?

I'm sure these still negatively impacted the opinions of folks who disagreed with them, but probably didn't make a Democrat start hating Musk then, or a Republican decide to hate Swift's music.

I do agree that they probably don't have much impact, through a 6-16% swing on a political position isn't nothing, either.
